Vyatta, a San Mateo start-up that sells an open-source router, said it has raised $7.5 million in a first round of financing.

The funding comes from JPMorgan Partners, ComVentures and ArrowPath Venture Partners.

Vyatta says its Open Flexible Router (OFR) is a more flexible and affordable alternative to the incumbent, “closed-source” products that dominate the market today. Vyatta’s stated goal is to bring “commercial-quality open-source networking products to market.”
